  • State 404 Program Applicant's Handbook
    STATE 404 PROGRAM APPLICANT’S HANDBOOK This Handbook, including Appendices A and B only is incorporated by reference in subsection 62-331.010(5), F.A.C. Effective [date] FOR: FLORIDA DEPARTMENT OF ENVIRONMENTAL PROTECTION Introduction The Florida Department of Environmental Protection (“Department” or “DEP”) developed this Applicant’s Handbook to help persons understand the rules, procedures, standards, and criteria that apply to the State 404 Program under Part IV of Chapter 373 of the Florida Statutes (F.S.). The Department administers and implements the State 404 Program. In the event the Department seeks and receives approval from EPA pursuant to 40 CFR 233.16 to modify the program to delegate implementation of the State 404 Program to Florida’s five Water Management Districts (“Districts”), the Districts may then implement the program with Department oversight. The State 404 Program Applicant’s Handbook refers to these entities collectively as “Agencies” and also refers to one or more water management districts as “District” or “Districts” (capitalized), respectively. The term “district” (lower case) generally refers to the main or field offices of either the Department or District. The Districts are: Northwest Florida Water Management District (NWFWMD) Suwannee River Water Management District (SRWMD) St. Johns River Water Management District (SJRWMD) Southwest Florida Water Management District (SWFWMD) South Florida Water Management District (SFWMD) The primary State 404 Program rules are adopted by DEP as Chapter 62-331 of the Florida Administrative Code (F.A.C.). This Applicant’s Handbook is incorporated by reference in subsection 62-331.010(5), F.A.C., and therefore operates as a rule of the Agencies.

  • Santa Rosa County Local Mitigation Strategy SECTION 3 HAZARD
    Santa Rosa County Local Mitigation Strategy SECTION 3 HAZARD IDENTIFICATION AND RISK ASSESSMENT 3.1 Santa Rosa County Local Mitigation Strategy This page intentionally left blank. 3.2 Santa Rosa County Local Mitigation Strategy HAZARD IDENTIFICATION AND RISK ASSESSMENT Introduction This section of the Santa Rosa County LMS summarizes the results of a hazards and vulnerability assessment process undertaken by the Task Force members and includes a description of the types of hazards that may affect Santa Rosa County, their probability of occurrence, the geographic locations that are vulnerable, the number of structures and population affected, and potential loss estimates. This information, gathered from a variety of sources, provides the best available data for describing and quantifying the potential impacts to Santa Rosa County and is consistent with the County’s Comprehensive Emergency Management Plan. Primary attention is given to natural hazards considered reasonably possible to occur in the County as identified thorough research by staff, input from members and citizens, and data provided by FEMA and other sources. These hazards include: Flooding (Hurricanes, Tropical Storms, and Thunderstorms) Severe Storms and Lightning (Including Hurricane Winds) Tornadoes and Waterspouts Wildfire Heat Waves and Drought Winter Storms and Freezes Erosion Tsunamis/Rogue Waves This update of the LMS omits hazards noted in prior versions that are unlikely to occur in Santa Rosa County. Those hazards are earthquake, avalanche, land subsidence, landslide, volcano, and sinkholes. The previous LMS also identified dam/levee failure as a separate hazard; however, the dams in Santa Rosa County are fairly small in size and impacts from failures fall within the broader hazard category of flooding.
